HKS LEA-MF6 Forged Piston & Con Rod Set

To improve the performance of the CR-Z using the factory connecting rods, the durability of the factory parts restricts the improvement. Using this Piston Kit and Connecting Rod Set with the HKS GTS7040 Set-up Kit can increase the maximum engine output to 300ps and the maximum torque to 36 kgfï½¥m; the CR-Z can be high performance hybrid sports car.
